| 中文摘要: |
| 为了详细研究淮南矿区冻土的物理力学性能，为冻结法施工提供设计参数，以刘庄煤矿东风井典型粘土层为研究对象，在冻结冻土力学性能室内进行了人工冻结的蠕变试验。根据冻土单轴蠕变实验数据，分析总结出冻土在单轴应力条件下的应力、应变、温度和时间相互作用的关系，从而得到蠕变本构方程和蠕变规律，该规律对淮南矿区井筒冻结设计和施工具有重要的借鉴意义。 |

| To study the physical and mechanical properties of permafrost in Huainan mining area and provide design parameters for frozen method, typical clay layer in East Wind Mine of Liu village is chosen as subject and creep test of artificial freezing is conducted in frozen soil mechanical properties room. According to uniaxial creep test’s data of permafrost, we analyze and conclude the relationship of interaction between stress, strain, temperature and time under the condition of uniaxial stress for permafrost. Then we get constitutive equation of creepage and rules of creepage, which may provide reference for pit-shaft’s frozen design and construction in Huainan mining. |
